HP laptop takes one hour to start POST.
While visiting friends in Florida this past week, one revealed a big problem with his HP Pavilion Dv7-1245dx, manufactured in 2009 with Vista installed.
When he turns it on from a cold start, the dashboard lights up, the cooling fan whirrs for about 3 seconds, then everything stops. Nothing but a black screen with the dashboard lights on. After about an hour, POST does occur and hands off to Vista - no problem.
Warm rebooting also has no problem. Right to POST and handoff.
Living with the one hour POST delay, I performed the following:
Long test disk check - passed
MemTest; 7 passes - passed
Opened up the bottom panel and removed the hd and memory sticks; cleaned all contacts and re-installed. The CMOS battery also happens to be available there with a little white plug-in, so I removed it for 30 minutes, pressed the power button, and re-plugged hoping it would enable a reset of the BIOS.
After waiting an hour, I did get the CMOS check sum error and reset defaults.
I then did a system recovery with his HP discs to factory condition.
I also removed the dvd drive.
All of the above activity did not solve the one hour POST delay.
I'm guessing a motherboard hardware fault somewhere?
Any ideas?
